To all whom it may concern Be it known that we, CHARLES E. Oxronn and JonN'A. Uronunon, citizens of the United'States, residing at Buckner, in the county of Lafayette, State of Arkansas, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivat'ors, oneof its objects being to providea simple and compact structure of this type utilizing means'whereby the teeth or shovels at the two sides of the central draft beam can be} adjusted 'angularly relative to saidbeam so as thus to throw the loosened soil toward or away from the rowsbetween which the machine is moving. I

Another'object is to provide means where by theseries-of-teeth or shovels located at the sides-59f. the beam can be adjusted horizontally'sdjzas'to engage-the ground along either forwardly or rea'rwardly converging A further o'bjeot 'isto provide a cultivator the parts of Which-can be easily. manipw.

latedv With the foregoing and other objects in view which will. appear as the description proceeds, theinvention residesm the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes'in 'the prec se embodiment of the im ention herein disclosed, can be made within. 'e--'scope of what is claimed, without idepartin'ggfrom' thespirit of the invention.

In the, accompanying drawings the preferred form of the invention has been shown. In said drawings :-Figure 1 is" a plan view of the "cultivator. Fig. 2 is a section on -lineaAe-'"B 'Fig. '1, said-section being enlarged.- Fig. 3 is an enlarged section on line C-D Fig. 1. :Fig. 4: is afview partly in elevation and partly in. section through the lowerend portion of one. of the adjustable braces. Fig. 5 is a front elevation of' ouc of the stem supporting e es. Fig. 6 is a rear elevation of one of the stem. supporting and engaging eyes. Fig. 7 is a perspective view of the front end-portion of one of the stems.

for engagihgthe. eye shown in Fig. Fig. 8 is an end .elevation of one of the locking elements used in connection with the barrow. Fig. 9 is a plan view thereof. Fig; 10 is a perspective view of one of the hinge plates;

Referring. to .t e figures by characters ofreference 1 designates the centraldraft beam of the cultivator, the same having handles 2.

diverging upwardly from the rear portion thereofand fixedly secured to the beam in any suitable manner. Secured to the bottom of the boomers front and rear hinge plates 1 3 to which are hingedly connected frontand rear straight arms 4 extending from the ends of .arcuate members -5 located at opposite sides of the beam 1. Each of these members 5 is formed in' its inner and outer edges with notches 6 arranged in pairs and, moreover, each of these arcuate members suppor't'sa slide in the form of a split sleeve 7 the end portions of which bear'downwardly on the arcuate members 5 and have notches 8 there-1- 1n adapted to register with any of the notches 6. These slides 7 have threaded studs 9 extending downwardly therefrom and secured to flat metal cross strips 10 hingedly connected, at their'inner cnds, to

plates 11 whichare arranged under beam 1" and each connectedthereto by a single pivot bolt 12 whereby the plate is free to swing relative to the beam 1. A post 13 extends upwardly from each of the front strips 10 and has a locking lever 14 pivotally connectedv to it, this lever .being provided with spaced lugs '115-adapted to extend downwardly into. the notches 8 and also into any of the notches 6 which may be registeringtherewith. With the lever thus positioned it will be seen that the strip 10 onwhich the lever is mounted and the slide 7 carried thereby are prevented from shifting about the bolt 12 or relative to the arcuatememher-5.

1 Each of the front strips 10 has eyes 16.

thereunder and connected thereto by threaded studs 17.- Each eye hasa conical counter bore 18 in its 'backface, this counter bore being toothed, as shown-in Fig. 6.

Plates 19 similar'to the plates 11 are arranged under beam.1back of the plates 11 and hingedl feonnected to these pivoted .plates 19 are oppositely extending strips 20 preferably formed of flat metal. .These strips extend under the arcuatemembers 5 this strips any suitable manner, as by -mbans of stems 22, the heads 23 of which are ,105 anrlfihave ves 21 thereunder connected to arranged within counter sinks in the upper faces ofthe strips'QO; .i-The' outermost ones of these eyes 21 may be providedv with threaded,studigfl instead of the stems 22, these studs extending looselyth'rough 'coni cal apertures 25 formed in the curved ends 26 of braces 27. Each brace is made up of" 'two.--.r01s connected by a turn buckle28, the inner rod 29 being loosely mounted on a' stem 30 projecting upwardly from-the beam i 1, said rods 29 being held on the stem by a nut'31 or'the like. Obviously by rotating. the turn buckles 28,- the outer ends of-the,

beam

strips can be swung upwardly or-permittcdfto swing downward-1y, thus ad ust1ng. the fstripsQO angularly relative to the Extending loosely-through the eyes 21 are cylindrical, stems 32 projecting forwardly- {many spring standards which. are curved downwardly and rearwardly-and either earl -en age the soil or are provided with.

--It WillFbeappa-rent th'atby: providing a structure such "as herein described, the standards 33 can =be-adjusted angularly about the longitudinal axes of :the s stems ,32

' and the strips '10 and QO-Zcan-be adjusted angulai'ly' jabout their connections .with the pares-11 and-19; Furthermoraby. disengaging-the levers'l l from the arcuate. menibers 5',"the' strips10= and 20 can be adjusted horizontallyso asto eause-the points of the T'teethor shovels to engage thesoil along lines converging either forwardly Or -rearv'v'ardly or alonga transverse or oblique line, as desired, By adpisting the outer endsof the strips 10 and- 20 dOWnWardlyor-upvvai'dl-y', the -'device can :be usedifor eultivating listed crops. Various othersusescan be found for the cultivator and which are, pos

sible by reason of the different adjustments which-c'an-bemade- The strips 10,-and 20 canbe'feonnected by pivoted braces 38..

A cultivator including a .centralibeam, oppositely disposed segmental members conne'cted'to the beam, a slide engaging eachof said members, front and rear cross strips extending beyond each side of the beam and soil engaging devices connected to said I cross strlps, means for'adjusting the cross strips angularly relative to the segmental members, and means for adjusting the cross strips angularly in aver'tical plane.

3. A cultivator'including' a beam, oppositely extending cross strips hingedly"con-' nested thereto, soil" engaging devices ,connected to the-strips, sectional braces loosely connected to the outer'ends'pf the cross strips and to the top "of the beamyand a turn buckle connecting the'sections of said braces for adjusting the cross strips angu- 4. A cultivator including a beam, front and re ar cross strips connected thereto, soil engaging devices having forwardly extending stems, means upon the rear cross strips for supporting the stems forrotation', each of said stems having a toothed'tapered portion at its front end anda stud projecting from said portion; means upon the front cross strips for receiving the'studs and tapered ends, said means having toothed tapered counter bores for engaging the taperedportion's' on 'the-stems,and m eans-en- I gaging" the studs forbinding said tapered portions of the stems Within the tapered .counter bores' In testimony, that We claimithe' foregoing natures 1n the presence of two witnesses,
